MEANS FOR REMOVING on. FROM EXHAUST STEAIl/l.

SPECIFICATION forming part of Letters Patent No. 316,673, dated April 28, I885.

v Application filed February 24. 1885. (No model.)

To all whom, it may concern.- Be it known that I, SINCLAIR STUART, of Plainfield, in the county of Union and, State of New Jersey, have invented anew and use ful Improvement in Means for Removing Oil from Exhaust-Steam, of which the following is a specification.

My invention is more particularly intended T for steamships, but may be employed where ever surface'condensers are employed in connection with steam-engines.

It is a fact well recognized by steam-engineers that the oil or grease which escapes with the exhaust'steam from steam-engines produces great injury to surface-condensers and the pumps by which the water of condensa tion is taken therefrom and delivered into the boiler, and that it oftentimes producesrapid wear and shortens the life of the boilers.

The object of my invention is to provide an attachment which may be applied to steamengines at small cost and by which all oil and grease will be caught or intercepted as they pass through the exhaust pipe or passage and separated from the steam and water of condensation, and, furthermore, to accomplish these desirable results without any loss of water of condensation, and without impairing the vacuum afforded by the condenser.

The means whereby these results are to be accomplished are shown in the accompanying drawings, and will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a partly sectional elevation of a steam-engine and appurtenances embodying my invention. Fig. 2 is a sectional elevation, upon a larger scale, of a part of the main exhaust-pipe having my attachment arranged therein or applied thereto; and Fig. 3 is a sectional elevation on the plane of the dotted line or m, Fig. 2.

Similar letters of reference designate corresponding parts in all the figures.

I shall only refer incidentally to the engine itself, as my invention does not involve any change therein beyond a slight alteration in the exhaust pipe or passage.

The engine herein shown comprises three cylinders, which may be of the compound variety, and which, with their steam chests and passages, are all formed in the cylinder structure A, which is supported on suitable framthe surface-condenser and pumps, which are of ordinary or any suitable construction.

In the exhaust pipe or passage 0 are placed any desired number of catch-plates or conductors, D. I have here shown four, which are arranged one above another and are inclined alternately toward opposite walls of the pipe or passage 0. These plates or conductors may be made of sheet or cast metal, and are preferably formed with corrugated or channeled upper surfaces, forming series of gutters or channels, which run in the direction in which the plates or conductors are inclined. The plates or conductors are, as stated, arranged on opposite sides of the pipe or passage, and overlap each other at their inner and higher ends, so that no steam can pass down through the pipe or passage without being repeatedly deflected or turned aside by them. At the same time they do not impede the circuitous passage of steam through the pipe or passage, being arranged one above an-. other.

The plates or deflectors D spring from or are attached at their lower ends to gutters or collectors a, from which pipes b b deliver all oil or grease and any water which may be in tercepted. The upper collectors or gutters a deliver their contents into the gutters below them by pipes b, and the pipes b from the lower gutters unite and deliver the oil and grease with any water which may be inter cepted through a pipe b and into a receiver or chamber, E, external to the pipe or passsage O.

The receiver or chamber E has at the bottom a pipe, 0, leading to the lower part of the exhaustpassage O or to the condenser, and in which is a cock or valve, 0. It should also be provided with a water-gage, d, and with one or more cocks, 6, (two being here shown,) for drawing off oil or grease. In the pipelb is shown a cock or valve, 22*, whereby the re ceiver or chamber E may be cut off from communication with the pipe or passage 0, when desired.

In the ordinary operation of the apparatus the valve 7)* isopen and the valve 0 is closed. Oil and grease, with some water, will flow along the conductors and pipes and into the receiver E. When the glass gage dshows the receiver to be about full, or at any desired time, the valve b* is closed and the valve 0 opened only long enough to permit the water of condensation, which will settle at the bottom, to flow therefrom until the water is below the lower cock e. That cock 6 is then opened and oil drawn off. This oil, if pure, may be again used as a lubricant. When sufficient oil has. been drawn off, the cock 0 is closed and the valve 12* opened to again allow l the receiver E to fill with oil and water.

; I or passage of a steam-engine, of catch-plates 7 and conductors arranged therein for intercepting oil and grease and conductingit to the exterior of such pipe or passage, substantially as herein described.

2. The combination, with the exhaust pipe or passage of a steam-engine, of inclined catchplates D, arranged on opposite sides thereof 5 alternately, collectors or gutters at the lower edges of such plates, and conductors or pipes leading therefrom to the exterior of the pipe or passage, substantially as and for the purpose herein described.

3. The combination, with the exhaust pipe or passage of a steam-engine, of catch-plates and conductors arranged therein for intercepting oil and grease and conducting it to the exterior of the pipe or passage, a receiver into which the oil and grease with water are delivered, a pipe leading from the receiver to the exhaust or condenser and provided with a valve, and a cock for drawing oil from the re ceiver, substantially as herein described.

4. The combination, with the pipe or passage O and the receiver E, provided with a gage, d, and one or more of the cooks e, of the system of catch-plates D in the pipe or pas sage G, the pipe b, delivering into the receiver, and the pipe and valve 0 c, for controlling the escape of water from the receiver, substantially as herein described. a
